Objectives. The histologic characteristics of the components of conducting portion and respiratory portion of the respiratory system. How these characteristics allow each component to contribute to the overall function of the respiratory system.
The respiratory system begins at the nose and ends at the distal alveoli. It is comprised of the upper and lower airways. The upper airway includes the nose, sinuses, and pharynx. The nose provides olfaction and temperature regulation in hyperthermic patients.
Diagnostic approach to a patient in respiratory distress should consider the patient’s signalment and history as well as the broad anatomic differential diagnoses of dyspnea (Table 1, page 54).
Respiratory System. ANS 215 Physiology and Anatomy of Domesticated Animals. I. Structure and Function of the Respiratory System. Respiration – means by which animals obtain and use oxygen and eliminate carbon dioxide. Respiratory apparatus 1. Lungs and air passages leading to them. nostrils. external openings for the paired nasal cavities.
20 Μαΐ 2024 · The primary function of the respiratory system is to deliver oxygen to the cells of the body’s tissues and remove carbon dioxide, a cell waste product. The main structures of the human respiratory system are the nasal cavity, the trachea, and the lungs.
histology of commonly reviewed organ systems, with the goal of illustrating important concepts of cells, tissues, and organs in a manner that we hope is not only accessible to first-year veterinary students, but serves as a reference for clinical medicine and pathology.
The evolution of the vertebrate respiratory system achieved its most efficient state in birds, with their constant volume parabronchial lungs and their highly compliant air sacs with low pressure ventilation that, enabling them to sustained flapping flight.
